Finally got the old tank dusted and purchased a new transmitter from FingerTech Robotics.
I think I saw a post here someone suggested buying from them, and for $45 can't go wrong!
I ordered a non-branded T6A v2 transmitter and got sent a Skyfly FS-CT6B, which I assume is the remodel of the old Hobbyking version. Looks identical.
Managed to get it binded to the old HobbyKing T6A receiver with ease.
Curious if people prefer to have the left stick self-center, as I did buy the "kit" in addition to the transmitter.
Guess it means I should get the wiring all cleaned up for a trip down in April to meet up again!
